INID

INID is an acronym for Internationally agreed Numbers for the Identification of (bibliographic) Data.

INID codes use Arabic numerals, and so are language-independent.

For example, number (30) indicates priority data, and (51) technical area according to the International Patent Classification (IPC).

[2] INID codes are standardised by World Intellectual Property Organization (WIPO) in ST.9.
